A complete selection to prevent risks

The manual alarm siren plays a vital role in protecting people. In the presence of extraordinary or threatening events, the alert siren is ideal for alerting people, especially when the site has no energy source. It is particularly suitable in campsites, schools, civil defense, but also for military defenses, mountain rescue and coastal alerts.

To benefit from optimal security on various projects and areas without electricity, the use of a manual siren meeting ATEX standards is essential. At Advanced Safety Solutions, you will find what you need, whatever your horn needs are! The technical sheets are available online and offer you practical information on all of our references. By purchasing a manual siren, you are choosing to provide an effective warning for applications where there is no power supply.

The advantages of manual sirens

Manual sirens have many advantages, especially for business sectors that require POI, PPI, PPMS plans.

The manual siren allows you to alert staff in case of danger, especially in areas without electricity. Indeed, no energy source is necessary to use it. In addition, its sound power makes it possible to broadcast a universally known alarm on large industrial sites, such as quarries or mines. Thanks to its shutter mechanism, the sirens we offer can provide more than three different warning signals.

Depending on the use and the sector of activity, opt for the manual siren LK-100 ideal for easy transport or the LK-100A for fast and solid fixing on a base. The LK-120 and LK120-A warning sirens with steel feet will be ideal for use at breast height.

Note that all our manual sirens are robust and compact for flexible use on your site.
